I say "no" in a pretty general way. I think that when kids watch shows too mature for them at a young age, it's not good. But I don't believe in the whole "if you watch too much TV you won't do well in school" thing. I watch quite a lot of television shows and make straight A's.

It's stupid if you think television is bad for kids. No offence but yeah lol

I think too much TV is bad for kids though.

television is just as good for kids as books are.

it not only depends on the show but it depends on the amount of television being watched.
different tv shows affect people in different ways... some people will watch the sopranos and it won't affect them at all, while others will start to develop more violent tendencies. but in general: a big problem with the content on tv is it desensitizes people to tragedy and inappropriate behaviors. people barely even flinch when they see a gun in a tv show or in a movie or unfortunately even when they hear about people being shot in real life. guns and violence, as well as cursing, drugs, and hyper sexual behavior have all become so main stream that our society has become so desensitized to it. it's scary how easily people play video games and just shoot their opponents and even physically beat them.
while watching tv might be worse for children than for adults...it can be really bad for adults as well. one of my co-workers is so ignorant and makes comments all the time like "the problem with kids these days is they watch too much tv." or "it's because of television that kids are having so many problems." yet she goes home from work and watches hours of television. and then there are the adults that say: "well i don't watch tv...i just watch the news and the history channel." guess what? that can be just as damaging to your brain cells as watching shows on the cw or on hbo. if you want to know the news...read the newspaper. if you want to learn about history...read a historical novel. reading stimulates your brain and can actually make you much smarter than watching tv.
so if you are going to choose to watch tv...i don't think you have the right to say that "kids shouldn't be watching tv." but i do agree that it's much better for kids to run around outside and play pretend games where they use their imagination or play games with other kids where they increase their social skills. when i was younger i watched tv...but i always preferred to play with my dolls, or play kickball, or play tag or run around outside than to sit inside and watch a tv show. it's unnatural for a child to sit still for hours without moving. so there is something scary about a child who can sit in front of a box and stare at it for 4 hours straight.

but is television going to destroy a child's youth? no. is it going to fry your brain? no. is it the cause of violence in schools? no.
but if any person watches too many hours of television per day...it can contribute to those factors-- but it definitely won't cause them.
